Abstract

The influence of Si and Al on the lattice parameter and stacking fault energy (SFE) of austenitic steel was studied. X-ray diffraction indicated that 2.5wt.% Al alloying increased the austenite lattice parameter by 1.41×10−3nm, whereas 2.5wt.% Si alloying had little effect. Partial dislocation separation measurements from weak-beam dark-field images indicated that 2.5wt.% Al alloying increased the SFE by 12–17mJm−2 and 2.5wt.% Si alloying decreased the SFE by 6–7mJm−2.
